A method for incorporation of arginase nanoparticles into mouse erythrocytes has been developed and the possibility of reducing blood arginine concentration in animals with experimental hyperargininemia with arginase-loaded erythrocytes (argocytes) has been studied. Argocyte infusion to animals with hyperargininemia led to a rapid decrease in blood arginine concentration within 1 h and this effect of argocytes persisted for at least 4 h. This was paralleled by an increase in plasma concentrations of urea and ornithine. Hence, plasma arginine is hydrolyzed by arginase incorporated into argocytes; argocytes are functionally active and can serve as a defense system in pathological hyperargininemia, while the method developed by us can be regarded as a new nanobiotechnology for medicine and veterinary.
